01
When is duct cleaning worth considering?
- Consider assessment when there is substantial contamination inside the system, pest evidence or excessive deposits on components beyond a single grille.
- Known construction debris after renovation can also justify a system review.
- Dust on a return grille alone does not establish that the whole air distribution system needs cleaning.
02
When should dryer exhaust be assessed separately?
Dryer exhaust is a separate system from HVAC air ducts. Assess it when venting is crushed or restricted, lint collects behind the dryer, the outside covering is damaged or the outside hood does not open during operation.
Slow drying alone is not a diagnosis. Use visible condition and access to decide whether a professional check makes sense.
03
When might cleaning not be the first step?
If the concern is moisture, wet insulation, mold-like growth, suspected asbestos or mechanical duct damage, specialist assessment or repair may come before cleaning.
A mold-like appearance is not confirmation of mold, and cleaning does not correct the moisture source that caused it.
These conditions need the right trade or professional, not a routine cleaning pitch.
04
How do you turn observations into a useful request?
- Describe the property type, exact address and whether the concern is HVAC air ducts, dryer exhaust or both.
- List observed evidence, such as debris, pest signs, restricted venting or a hood that does not open.
- Include known duct material, prior cleaning or repairs, and any access limits.
- Ask for a written scope with inclusions, exclusions and approval before added work.
